ABSTRACT
The objective of this study was to evaluate the relationship between variations of the lateral wall of the nasal cavity and septal deviation (SD). Coronal and axial paranasal sinus CT images of 115 individuals (65 females, 50 males) were reviewed and the presence of pneumatisation and hypertrophy of the conchae was evaluated. Pneumatisation of the concha was classified as lamellar concha bullosa (LCB), bulbous concha bullosa (BCB), or extensive concha bullosa (ECB). If bulbous and extensive conchae and hypertrophic conchae were bilateral the side on which it was greatest was accepted as the dominant concha. The relationship between these variations and nasal septum deviation was also taken into account. Eighty-six (74.8 percent) of the 115 subjects had SD. Of these, 20 were not affected by the size of the middle nasal concha (MNC) or inferior nasal concha (INC). Thirty-four cases had dominant MNC, 20 had dominant INC, and 11 had both dominant MNC and dominant INC, and all of which had SD towards the opposite side. In one case there was SD towards the side in which the MNC was dominant. Our data indicate that coexistence of pneumatisation or hypertrophy of the conchae and SD was more common in adults compared to the results of similar studies conducted with a wide range of age groups, including children. Thus the presence of SD together with a large concha increases with age. A prospective study, which will include infants, will elucidate the relationship between conchae and SD.
El objetivo del estudio fue evaluar la relación existente entre las variaciones de la pared lateral de la cavidad nasal y la desviación septal. Se revisaron los senos paranasales en imágenes de TC de 115 individuos (65 mujeres, 50 varones) coronales y axiales y se evaluó en ellas la presencia de neumatización e hipertrofia de los conchas nasales. La neumatización de la concha fue clasificada como concha laminar bulosa (CLB), concha bulbosa bulosa (CBB), o concha extensa bulosa (ECB). Conchas nasales bulbosa y extensa y conchas hipertróficas eran bilaterales siendo el lado en que esta era más grande como la concha dominante. También se tuvo en consideración la relación entre estas variacio nes y la desviación del tabique nasal. Ochenta y seis (74,8 por ciento) de los 115 sujetos tenían desviación septal. De éstos, 20 no se vieron afectados por el tamaño de la concha nasal media (CNM) o concha nasal inferior (CNI). Treinta y cuatro de los casos tenía CNM dominante, 20 tenían CNI dominante, y 11 tenían tanto CNM dominante y CNI dominante, todos los cuales tenían desviación septal hacia el lado opuesto. En un caso hubo desviación septal hacia el lado en el que el CNM era dominante. Nuestros datos indican que la coexistencia de neumatización o hipertrofia de conchas nasales y la desviación septal es más común en adultos en comparación con los resultados de estudios similares realizados con una amplia gama de grupos etarios, incluidos los niños. Así, la presencia de desviación septal, junto con una gran concha aumenta con la edad. Un estudio prospectivo, que incluirá los bebés, aclarará la relación entre concha nasal y desviación septal.

OBJECTIVES: Since few studies on surgical training and learning curves have been performed, majority of inexperienced surgeons are anxious about performing operations. We aimed to access the results and learning curve of septoplasty with radiofrequency volume reduction (RFVR) of the inferior turbinate. METHODS: We included 270 patients who underwent septoplasty with RFVR of the inferior turbinate by 6 inexperienced surgeons between January 2009 and July 2011. We analyzed success score, cases of revision, cases of complication, operation time, and acoustic rhinometry. RESULTS: Success score was relatively high and every surgeon had few cases of revision and complication. No significant difference was found in success score, revision, complication case, or acoustic rhinometry values between early cases and later cases. Operation time decreased according to increase in experience. However, there was no significant difference in the operation time after more than 30 cases. CONCLUSION: We can conclude that 30 cases are needed to develop mature surgical skills for septoplasty with RFVR of the inferior turbinate and that training surgeons do not need to be anxious about performing this operation in the unskilled state.

Deviated nasal septum is associated with compensatory hypertrophy of the inferior nasal concha on the contralateral side. In the past conventional septoplasty was done for the deviated septum, which would improve the patency on the side of deviation but would worsen it on the opposite side due to reallocation of the septum to the midline. The present study of 50 patients unfolds the anatomical composition of the inferior nasal concha based on the computed tomographic scan and help the otolaryngologist to determine whether to add turbinoplasty to standard septoplasty procedure or not.
Un tabique nasal desviado está asociado con una hipertrofia compensatoria de la concha nasal inferior del lado contra lateral. En el pasado se realizaba septoplastía convencional para el tabique desviado, lo que mejoraraba la permeabilidad en el lado de la desviación, pero agravaba ésta en el lado opuesto, debido a la reacomodación del tabique en el plano mediano. En el presente estudio se evaluó en 50 pacientes la composición anatómica de las conchas nasales inferiores, basado en la exploración a través de tomografía computarizada, y de esta manera ayudar al otorrinolaringólogo a determinar si es necesario o no, añadir la plastía de la concha nasal inferior al procedimiento de septoplastía estándar.

Objective To observe the efficiency of radiofrequency ablation on inferior nasal concha hypertrophy under nasal endoscope.Methods The radiofrequency ablation needle was applied to inferior nasal concha under 0? nasal endoscope.Results Nasal obstruction was evidently improved,the volume of inferior nasal concha became normal,and the surface became smooth 4 weeks after operation.Efficiency was assessed according to nasal obstruction visual analogue scale(VAS),in which the scale was significantly reduced from(7.9?1.0)points preoperatively to(4.1?0.9)points at 6 months postoperatively(t=2.316,P=0.027).Conclusions Radiofrequency ablation is an effective alternative to treat inferior nasal concha hypertrophy under nasal endoscope.
